JOHN H. SWIHABT, OF 'BEAVER FALLS, PENNSYLVANIA.

GAS-HEATER.

Application filed May 16, 1916.

To all whom t may concern.'

Be it known that I, Jol-IN H. SwIi-mn'r, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Gas- Heaters, of which the following is a specification.

This invention relates to new and useful improvements in gas heaters and has for its object to provide a gas heater which is simple, practical and economical in construction and which will produce the maximum heat with the minimum amount of fuel consumption.

W'ith the foregoing and other objects in view that will appear as the nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts illustrated in the drawings and more particularly pointed out in the appended claims.

in the accompanying drawings:

Figure 1 is a vertical transverse section of a gas burner embodying my improvements, taken on line 1--1 of Figs. 2 and 1i.

Fig. 2 is a horizontal section, taken on line 2-2 of Fig. 1.

Fig. 3 is a vertical transverse section, taken on lines 3 3 of Figs. 2 and et, and Fig. 4 is a horizontal section, taken on line 4 1 of Fig. 1.

ln the embodiment illustrated, the burner comprises a cylindrical perforated casing 1, the lower end of which closely lits the upper cylindrical portion 2 of the supporting band 3, and the lower edge of which rests on the horizontal ange 4, which connects the upper cylindrical portion 2 of said band with the lower outwardly flared portion 5 thereof. The lower end of the casing 1 and the upper straight cylindrical portion 2 of the supporting band 3, are secured by bolts and nuts 6 and 7, or other equivalent means, to the vertical extensions 8, formed at the upper ends of the vertically disposed inwardly inclined supporting legs 9, which, in the present disclosure are four in number, and are spaced equidistances apart around the circumference of the casing. The supporting band or ring 3 is provided at its lower edge with a plurality of depending legs 10 corresponding in number to the supporting legs 9, the former fitting against the outer faces of the upper inwardly oset portions Specification of Letters Patent.

11 of the latter and being secured thereto by the bolt and nuts l2 and 13, respectively.

The horizontal burner 14, which is of circular form or outline and of cylindrical form in cross section, is provided in its top with a series of vertical transverse circumferentially spaced ports or openings 15 for the egress of the gas and is arranged hori- Zonta-ily in position within and opposite the lower outwardly flared portion 5 of the supporting band 3 and is supported in place by a plurality of outwardly projecting radially disposed lugs 16, four in the present case, which are spaced equidistances apart around the outer edge of the burner and are received by corresponding recesses 17, forme-d in the thickened portions 18 of the supporting legs 9, such thickened portions being situated immediately below the straight vertical extensions 8 of said legs. The burner let is also provided at its inner edge with a series (four in the present instance) of inwardly extending spacing lugs 19 which are spaced equidistances apart and provide a means of centering the lower end of a hollow inverted cone shaped heating drum or tube 20, which is arranged vertically within the casing 1 and is tapered gradually from its eXtreme upper to its lower end.

As shown, the upper edge of said heating drum or tube may be clamped to the upper edge of said casing 1 by the inwardly bent flange 21 of the latter. The drum or tube 2O terminates at its lower end in a reduced cylindrical extension 22 which is received by the upper tubular extension 23 of the hollow inwardly flared deflector 2e supported at its lower edge by the inwardly extending lugs 25 formed on the inner faces of the supporting legs 9 near the lower ends of the latter.

The burner le is provided at a suitable point, with a horizontal outwardly projecting supply tube 26, which is cast integral with the burner and terminates at its outer end in a nozzle 27 to which the gas tube is connected, the supply tube of the burner being also provided at its outer end with a cock or valve 28, the purpose of which is obvious and with an air mixer 29, of any suitable form, which has a threaded and adjustable connection with said supply tube.

It will also be observed that the heating drum or tube 20 is provided at diametrically opposite points, with a pair of vertical fiat wings 30, which are suitably secured or attached at their inner edges to the outer surface of the heating druin or tube and extend approximately the length of the perforated portion of the casing 1, the purpose of which wings is to prevent cross drafts inside the casing.

In practice, the heated air which is caused by the flame evolved by the burner, as well understood, passes upwardly and radiates outwardly through the perforations of the casing l. The flame and the air thus heated also heats the drum or tube 20, which by heating the air within the drum or tube causes it to rise and in this way establishes a suction or continuous draft of air through the drum or tube which is heated in passing therethrough and plays its part in heating the rooin, the air being directed to the lower end of the heating drum or tube by the deflector 24.

From the foregoing description taken in connection with the drawings, it is thought that the construction and operation of this invention will be readily understood without requiring a more extended explanation.

Having ldescribed my invention, what I claim as new and desire to secure by Letters Patent, is

l. A gas heater of the character specified comprising a perforated casing, a supporting band or ring closely fitting the lower end of the casing and provided with an outwardly flared depending portion, a gas burner of circular outline and provided in its top with vertical discharge ports or openings, arranged horizontally within the outwardly flared depending portion of the supporting band or ring, a supply tube leading to the burner, supporting legs for the casing and supporting ring, a downwardly flared hollow drum or tube arranged vertically within the casing, a deflector supported by the supporting legs and connected with the lower end of said drum or tube, the deflector in turn supporting said tube, a plurality of spacing lugs formed on the inner edge of the burner for centering the lower end of the heating drum or tube and interlocking means formed at the outer edge of the burner and in the inner faces of the supporting legs whereby the burner is removably supported by said legs.

2. A gas heater of the character specified comprising a perforated casing, a supporting band or ring closely fitting within the lower endy of the casing and provided with an outwardly flared depending portion, a gas burner of circular outline and provided in its top with vertical discharge ports or openings arranged horizontally within the downwardly flared depending portion of the supporting band or ring, a supply tube leading to the burner, supporting legs for the casing and supporting ring, a downwardly flared hollow drum or tube arranged vertically within the casing, a deflector supported by the supporting legs and connected with the lower end of said drum or tube, the deflector in turn supporting said tube, a plurality of spacing' lugs formed on the inner edge of the burner for centering the lower end of the heating drum or tube, interlocking means formed at the outer edge of the burner and in the inner faces of the supporting legs whereby the burner is removably supported by said legs and a pair of flat vertical wings secured to the outer surface of the heating' drum or tube within the casing at diametrically opposite points to prevent cross drafts within the casing.

8. A gas heater of the character specified comprising a perforated casing, a supporting' band or ring closely fitting within the lower end of the casing and provided with an outwardly flared depending portion, a gas burner of circular outline, arranged horizontally within the depending portion of said band or ring, supporting legs formed with offset upper end portions to receive and support said band or ring, said offset portions provided in their inner faces with horizontal recesses, a downwardly flared hollow drum arranged vertically within the casing, a deflector supported by said supporting' legs and connected with the lower end of said drum or tube, a plurality of spacing' lugs formed on the inner edge of the burner for centeringthe lower end of the heating drum and radial lugs formed on the outer edge of the burner and received by the recesses in the offset upper end portions of the supporting legs whereby said burner is supported.

In testimony whereof I afX my signature in the vpresence of two witnesses.
